Army Plans Awards, Solicitations for Assured PNT with(out) GPS

The U.S. Army will soon release new contracts and a post-Milestone B solicitation as part of its shift to a system of systems approach for making sure warfighters have the position, navigation, and timing (PNT) information they need regardless of issues with getting the GPS signal.

The Assured PNT (APNT) approach incorporates multiple sensors and an open architecture into an integrated whole that is resilient and easy to update, explained Kevin Coggins, the direct reporting program manager for PNT.
